I'd like to put an exterior light fixture between my two garage doors. The spot where it "belongs" has a post made of six (!) sistered 2x4s in the wall (presumably supporting the headers for the garage doors) and I'm looking for a way to get a wire from a shallow box (set into the 3/4" wood siding) into the empty space next to the post. I could drill a hole on an angle, but it would have to penetrate at least two of the 2x4s, and I'm concerned that may compromise their strength too much.
What options do I have (if any) for a light in this spot?
